  journal={Physical Review Letters},
We investigate a novel stochastic technique for the global optimization of complex potential energy surfaces (PES) that avoids the freezing problem of simulated annealing by allowing the dynamical process to tunnel energetically inaccessible regions of the PES by way of a dynamically adjusted nonlinear transformation of the original PES. We demonstrate the success of this approach, which is characterized by a single adjustable parameter, for three generic hard minimization problems.

Quantum path minimization: An efficient method for global optimization

A new unbiased global optimization approach is proposed, based on quantum staging path integral Monte Carlo sampling and local minimization of individual imaginary time slices. This algorithm uses

Global Optimization by Adiabatic Switching

We apply a recently introduced method for global optimization to determine the ground state energy and configuration for model metallic clusters. The global minimum for a given N–atom cluster is

Global optimization on an evolving energy landscape.

In application to a model problem, finding the ground-state configuration and the energy of rare-gas (Lennard-Jones) atomic clusters, the utility and the efficacy of the homotopy method are demonstrated.

Energy landscape paving simulations of the trp-cage protein.

A temperature-free variant of the method is introduced and it is demonstrated that it allows a fast scanning of the energy landscape and Nativelike structures are found in less time than by other techniques.

Reproducible protein folding with the stochastic tunneling method.

A novel version of the stochastic tunneling method and a recently developed all-atom protein free-energy force field are used to reproduce the reproducible folding of the 20 amino-acid protein trp cage.

Multicanonical jump walk annealing: An efficient method for geometric optimization

A new global optimization method, multicanonical jump walk annealing (MJWA), is proposed and applied to the geometric optimization of Lennard-Jones and Morse clusters and the hydrophobic (B),

Sampling Protein Energy Landscapes – The Quest for Efficient Algorithms

This chapter reviews strategies for faster sampling and discusses their limitations, and recent applications to protein folding document the utility of the described techniques.
